We want to turn now to a new study about social media, specifically Facebook. You've probably seen that the site is unbelievably popular among college students. You can find them posting updates on the bus, chatting in the library, tagging photos while they walk. But even though nearly every student has Facebook, there's a new study that says different groups use the site in many different ways. And according to the study, at least, that can have surprising implications for student success in college and even beyond.
